/frv400/v2_0/ChangeLog
0,0 → 1,71
2002-05-30 Jonathan Larmour <jlarmour@redhat.com>
 
* include/devs_eth_frv400.inl: Use CYGINT_IO_ETH_INT_SUPPORT_REQUIRED
instead of CYGPKG_NET where required.
 
2002-03-28 Gary Thomas <gthomas@redhat.com>
 
* cdl/frv400_eth_drivers.cdl: Don't define CYGHWR_NET_DRIVERS as this
is done in the generic driver.
 
2001-12-10 Richard Sandiford <rsandifo@redhat.com>
 
* include/devs_eth_frv400.inl (_frv400_eth_int_clear): Don't
unmask the interrupt after clearing it.
 
2001-10-16 Gary Thomas <gthomas@redhat.com>
 
* include/devs_eth_frv400.inl: Specify buffer layout (change in
generic driver requires this).
 
2001-10-15 Gary Thomas <gthomas@redhat.com>
 
* include/devs_eth_frv400.inl: Allow configuration to force ESA
(in case EEPROM is bad), otherwise make sure EEPROM is used to
set chip address (ESA) before use.
 
2001-10-12 Gary Thomas <gthomas@redhat.com>
 
* include/devs_eth_frv400.inl: Add PCI scanning for device.
(_frv400_eth_int_clear): Need explicit interrupt acknowledge.
 
2001-10-10 Gary Thomas <gthomas@redhat.com>
 
* include/devs_eth_frv400.inl:
* cdl/frv400_eth_drivers.cdl: New device driver for onboard LAN,
based on RTL8029s which is the same as DP8390 (NE2000).
